What type of energy requires a uranium and a reactor?

This cost depends on: type of reactor, type of the fuel, electrical power of the reactor, enrichment of uranium, the year of reactor project, global and local economic situation, etc.

There are many types of uranium pellets depending on the nuclear reactor type and the used uranium enrichment (or uranium-235 content). It may be more illustrative to say that: 1 gram of uranium-235 when undergoes fission in a nuclear reactor gives energy roughly equivalent to burning 3 tonnes of coal or 2 tonnes of oil.

radioactive element like uranium, plutonium......etc depends which type of nuclear reactor.

The mass of uranium needed for a nuclear power reactor depend on the type and the power of this reactor. For a medium size reactor - 100 t.

Depending on the type and the power of the nuclear reactor. An example; a CANDU type reactor of 700 MW need 700 kg uranium-235 and only ca. 500 kg are "burned".

Yes, it is possible; see the link below. But uranium is used in this type of reactor not as a fissile material but as a fertile material (the isotope 238U).

Uranium is used in nuclear reactors in the form of small cylinders (pellets) of sintered uranium dioxide (but other type of fuels also exist). The way from the mine to reactor is long an difficult.

Uranium is a source of nuclear energy.

Uranium is an element, not energy. It can be converted into energy by nuclear fission.

Approx. 1-2 years, depending on the type of reactor and fuel.

Depending on: - the type of the nuclear reactor - the electrical power of the nuclear reactor - the type of the nuclear fuel - the enrichment of uranium - the estimated burnup of the nuclear fuel etc.

Depending on the reactor type: 1-2 years.

Depending on the reactor type and power: from 1 kg to more than 100 000 kg.

This type of energy is called fission energy.

The quantity depends on: the type of the reactor, power of the reactor, enrichment of uraniu, chemical form of the fuel, etc. For a research reactor some kilograms, for a power reactor more than 100 tonnes/year.
